PG-1482, PG-1289 Add coverage to repo and percona server version check. (#212)

- Added code coverage to link repo to codecov.io for coverage stats on
PR and merge.
- Added coverage badge on the landing page (readme) of the repo. 
- Updated GH action to run on PUSH/MERGE, as this is required for code
coverage.
- Updated bash files in ci_scripts folder to accommodate tde
installcheck only.
- Added percona server version scheme verification TAP test case.
